say if grep can find non-ascii

[Dan Jacobson]

The grep manual page should say how to do
$ perl -nwe 'print if /[^[:ascii:]]/'
but with grep. Or say if there's no way.
Never mind this:
$ grep -P '[^[:ascii:]]'
grep: The -P option is not supported
C> address@hidden is probably the right place to ask.
Well I was just doing as the man page on Debian sid said.
